Typical faults of beamers and their solutions
DLP Projector / Pixel error / Start-field:
A typical error that occurs in DLP projectors, produced since 2007, is an increasing number of white or black dots , which appear constantly during the projection.
Total loss! We could replace the DLP chip (200-650€ incl. service), but unfortunately the problem will occur after 3-36 months again sometime, also regardless of the use!
In their first 20 years of production DLP chips were unbreakable. We have seen units with 50,000 hours or more. Since 2007 there is a new convenient design of DMD-chip, which after 3-4 years gets ruind and has the error described above .
LCD Projection error:
Typical faults in LCD projectors are image errors such as bright colour stains white background, colour spots on the image or other defects that are visible on the projected image.
Repairable and worth it! There is mostly dust in the optical system or defective LCD’s and polarizing filter. These are usually repairable damages.Here it is worthwhile to send the unit to us for reviw. Most times we can offer here a quick, convenient repair.
DLP or LCD projector does not make a sound. power supply defective!
If your device is unresponsive, no light bulb or the lamp is not ignited, it is often a power supply failure. Its repairable and worthwhile fixing it! As long as the motherboard was not damaged, it is very easy to repair. We have a lot of power supplies and lamp power supplies in stock, in sometimes we can replace the defective component on the power supply. Send us your defective device and we will get your projector up and running again.
